A grinding wheel is a wheel composed of an abrasive compound and used for various grinding abrasive cutting and abrasive machining operations.Such wheels are used in grinding machines.The wheels are generally made from a composite material consisting of coarse-particle aggregate pressed and bonded together by a cementing matrix called the bond in grinding wheel terminology to form a.
But resin bond grinding wheels have low hardness.If put the resin grinding wheel into the paraffin wax, it can prevent the influence of alkaline solution.In addition, when the temperature is higher than 150, the resin bond will soften and reduce its strength, even burn.Therefore, it should be cooling when grinding.
Cbn is great for grinding most grade of steels, but they must have a hardness of 45rc or above to be ground effectively with cbn.Stainless steels have been found to be ground effectively and profitable with cbn resin bond wheels.Unlike diamond, cbn wheels do not react to iron, so ferrous materials are not a problem when using cbn.
Besides, grinding wheels hardness also affect the adhesion of abrasive grains and stainless steel.The higher the hardness of the grinding wheel is, the more serious the adhesion degree of the grinding wheel will be.Certainly, the grinding wheels hardness cannot be too low, which may result in fast abrasion.Since stainless.

Bonded abrasives are natural or synthetic abrasive grains bonded into a solid form, usually in the shape of a wheel.The chart shows the hardness grade for grinding wheels.Grain conversion chart for grinding wheels.The conversion chart for different grains used for grinding.
Hardness of grinding wheel is specified by an alphabet q-z -high grade - hard wheels - used for soft and ductile materials j-p - medium grade a-i- soft grade - soft wheels - used for hard and brittle materials.Is this answer correct 1 yes 0 no post new answer.
A grinding wheel is designated coarse, medium, or fine according to the size of the individual abrasive grains making up the wheel.Bonding material bond the abrasive particles in a grinding wheel are held in place by the bonding agent.The percentage of bond in the wheel determines, to a great extent, the hardness or grade of the.
